How to compare round gem and shaped bases
Check the base’s span and construction separately from the published body measurements.
Look for the external outline
A round gem and a shaped ornament need different descriptions. Ask for the widest and narrowest spans across the base. For a shaped base, check how far the surrounding material extends beyond the ornament.
Check how the parts meet
The listing labels the main body aluminum alloy and names ABS plastic among the materials. Inspect where the decorative trim meets the base and follow the model-specific care instructions. Set the item aside if any trim loosens.
Keep base dimensions separate
The 1.6-inch figure describes body width on the listed products. Confirm the span of the external flared base separately. For more examples of different base footprints, see the plug base measurement guide.
